Company Profile

Product Overview

 

Engineered exclusively for the iPhone 14 Pro Max, this user-friendly 3.86V 4323mAh lithium-ion battery features next-gen high-density cells and an intelligent power management chip. While strictly adhering to Apple’s original voltage standard (3.86V), it optimizes cell structure and circuitry to deliver a 4323mAh capacity (typical), extending runtime by approximately 22% compared to the previous OEM battery—perfect for power users demanding all-day performance.

 

Certified by UL, CE, and RoHS, it integrates seven-layer smart protections (overcharge/over-discharge/short-circuit/over-temperature/over-voltage/over-current/cell health monitoring) with AI-driven power regulation, ensuring stable output in extreme conditions (-10°C to 50°C) while slowing degradation for a 3+ year lifespan.

 

The battery’s housing combines aerospace-grade aluminum alloy framing with fire-retardant V0-rated PC material, crafted via precision CNC machining for a flawless fit inside the iPhone 14 Pro Max—no gaps, no rattling.

It supports 100% system battery display and native 27W fast charging, compatible with all iOS updates—no popup warnings or functional limits. Each unit undergoes 96-hour full-temperature aging tests and 1,500 charge-cycle validations to guarantee zero defects, making it the ultimate choice for premium users prioritizing safety and endurance.

 

Application

 

•Heavy Usage Scenarios: Ideal for gamers, video creators, and professionals needing prolonged high-load performance. A full charge supports up to 8 hours of gaming, 5 hours of 4K video recording, or 14 hours of 5G browsing—eliminating battery anxiety.

•Business Travel: The 22% larger capacity extends runtime by 6–8 hours, paired with car chargers or power banks for seamless connectivity during international flights or long meetings.

•Outdoor Adventures: Maintains over 90% capacity in extreme temperatures (-10°C to 50°C), powering GPS navigation, emergency alerts, and other outdoor essentials for hiking, camping, or off-roading.

•Home Backup: Serves as a spare battery for living rooms or offices, enabling quick swaps when the main battery dies to avoid missing calls, payment verifications, or smart home controls.
